How to call a different constructor conditionally in Java?

Question

Let\'s say someone gives you a class, Super, with the following constructors:

public class Super
{
    public Super();
    public Super(int arg)         


        

Answer 1

You can't do that, but you can do this from the code that calls your class:

        if (some_condition_1)
            new Super();
        else if (some_condition_2)
            new Super("Hi!");
        else if (some_condition_3)
            new Super(new int[] { 5 });
        else
            new Super(arg);
